A method for the fixation of a permanent pervenous electrode for atrial pacing, comprising the steps of inserting an inspection catheter into the right atrium to determine the optimum position inside the right atrium for the fixation of a pervenous electrode, causing a guidewire slidably built in the inspection catheter to be forced out and allowed to form a loop along the endocardium of the right atrium, inserting into the right atrium an induction steel wire via a double lumen needle pierced through the chest wall in the direction of the loop of guidewire, causing the loop to tighten around and catch firm hold of the induction steel wire and withdrawing completely the inspection catheter while the induction steel wire is held in a state caught fast in the contracted loop of guidewire at the end of the catheter, replacing the inspection catheter with the permanent pervenous electrode, drawing the steel wire backwardly and thereby introducing the pervenous electrode into the right atrium and suturally fixing the pervenous electrode at the aforementioned optimum position.
